REED FOR WEAVING-LOOMS.

To all whom it may concern:

Be it known that I, MONTAGUE TABOR PICK- STONE, of 64 Alexandra road, Hamp stead, in the .county of Middlesex, England, have invented certain new and useful Improvements, in Reeds for Weaving-Looms, of which the following is a specification.

This invention relates to weaving looms in which the shuttle is operated pneumatically and the chief object of the present invention an improved reed which will guide the shuttle positively as it traverses across the width of the loom from shuttle box to shuttle box.

The invention comprises a reed the mem bers of which are so formed or shaped as to provide a race from which the shuttle is prevented from escaping otherwise than longitudinally, the reed plates, which constitute the reed, being undercut at the ends to engage with similar grooves in the supportingrails; V

The accompanying drawing shows in cross seotiona-reed constructed according to this invention, the reed being shown employed in a loom in which the warp threads ascend in an approximately vertical line from the beam to the fell of the cloth. With reeds of the type indicated a. shuttle of tubular form is employed as indicated at A. The.

number of metal plates The members'Bhave crescent shaped holes or cut-out portions formed in them centrally providing the horns or inward projections B, B. The distance between the horns B, B'- is less than the diameter of the shuttle, so that the latter can only move longitudinally in the race. The warp threadsshown in an open-shed position-are indicated at Wthe heddle eyes at H and the fell of the cloth at D. The reed members B are held in position by two grooved rails C; the ends B of the reed members B are dovetailed to fit into the groove C of C as Specification of Letters Patent.

shown. With this type of reed the ordinary shuttle race provided by the upper face of the slay is dispensed with.

It is already shown by my prior specifi cations of British Patents No. 4507 of 1909 the shuttle rising out of the groove, andplaltes are threaded upon side supporting roc s.

What I claim as my invention and desire to protect by Letters Patent is 1. In a loom, a combined shuttle race and adapted to guide the shuttle positively as it travels across the loom, comprising a plurality of reed plates arranged parallel to each other having crescent formed in them to secure the prevent its escape otherwise than longitudinally while their ends are undercut to engage with undercut grooves in supportmg rails.

2. A reed for weaving looms comprising a plurality of reed plates mounted parallel to each other, the plates each havinga cut out shaped holes portion alined with the adjacent plates to guiding the shuttle poslform a race for tively across the loom, vided by said out out ing escape of the shuttle from the race laterally thereof.

3. A reed for weaving looms, comprising a plurality of reed plates mounted substantially parallel to each other, I ing a crescent shaped cut out -p0rt10n in one edge thereof providin tions at said edge of the'p ate, said cut-out and means also proportions being alined to form a shuttle race,

the distance between said projections being greatest diameter of the race.- In testimony whereof I have aflixed my signature;
